Kawamoto Pump Mfg. Co., Ltd.

Submersible(drainage)

DUG2/DU2/DU4/DUM2

Adopting new developed small & high torque motor, and urethan rubber for Impeller so that is strength to lubrication, it performs excellent pump characteristics.
Aluminum die casted motor frame and adopting rubber materials brings weight and size down.
Vortex structure relieves Impeller lock from sand, and easy disassemble and assemble.
Built in auto-cut prevents motor from burn.
